Oh - I see now I should have been more specific with my question.
You're talking about the "don't use soap envelope" issue...
SOAP is not an option in my scenario.
We must use HTTP (with GET method) and therefore my question was to be understood like "did you find a solution for the http adapter".
But I realize now that you proceeded down the soap adapter path and hence never pursued a solution for the http receiver adapter.
Thanks for the answer anyway
